目的 探讨病毒性脑炎(下称病脑)不同病情临床影像学改变与临床的关系。方法 对132例不同病情病脑头颅CT、MRI与临床表现进行分析研究。结果 头颅CT检查122例,异常74例,异常率60.65%。MRI检查16例,异常15例,异常率93.75%。MRI的改变比CT更加明显。病情轻者CT基本正常,但MRI则可有改变。病情中度者以累及灰质为主,表现为灰质肿胀。病情重者同时累及灰、白质。极重度者可伴脑出血。临床疗效好者影像学改变轻,疗效差者影像学改变明显,并发症与后遗症发生率高。结论 病脑患儿头颅CT、MRI检查,尤其MRI对该病的诊断、病情轻重及预后有重要意义。
Objective To investigate the relationship between clinical imaging changes and clinical manifestations of different encephalitis in patients with viral encephalitis. Methods The brain CT, MRI and clinical manifestations of 132 cases with different disease were analyzed. Results The cranial CT examination in 122 cases, abnormal 74 cases, the abnormal rate of 60.65%. MRI examination in 16 cases, abnormal in 15 cases, abnormal rate of 93.75%. MRI changes more clearly than CT. CT mild condition normal, but MRI may have changed. Moderate to mainly gray matter involvement, manifested as gray swelling. Severe cases involving both gray and white matter. Very severe may be associated with cerebral hemorrhage. Clinical effect of good imaging changes in patients with mild, poor efficacy of significant changes in imaging, complications and sequelae of the high incidence. Conclusion The brain CT, MRI examination in children with brain diseases, especially MRI, is of great significance in the diagnosis, severity and prognosis of the disease.
